TIRE ItEil'lIUVING AND REPLAHING DEVICE.

Specification of Letters Patent.

li e-tented lice. ii til-116 Application filed Marci. 4., 1915. Serial No. 12,115.

. a resident oi the citv of St. Louis, State of eouri, have invented certain new and use improvements in Removing and placing Devices, of which the following a toll. clear, and exact description, referice being had to the accompanying drawtwining a part of this specification.

.e igure 1 is a fragmentary front elevation showiz'ig the device applied to an expansible tire rim. 2 is a side elevation of the ,arts shown in Fig. 1. Fig. 3 is a view of elements near the center of the device, the back cover plate of the housing being removed and some of the elements being "ted to expose the vertical rack arms. t is vertical section taken approxiely on the line i- Fig. Fig. 5 is enlarged detail view showing the outer rack arm. Fig. 6 is a detail 1m :1 the rim. of a wheel and fragot the riinreceiving members shown 5.

1i. desiates a central body or housing zided with hearing it for a shaft shaft is rotatably mounted in the front rear Walls of the housing; H. The rear l is removable and does not appear in 3 and 4. A pinion. B, located at the center of the device, is fixed to the shaft designates an operating handle secured to one end of the shaft Rack arms 0,

r r... Cw: P...

3 meshinn with the pinion B, are arranged tangential to the central. opening in the housing H. These rack arms pass through openings, or channels, in the housinfi' ll.

' {Z designates a circular plate arranged within the housing and fitted to an annular c, the latter being formed integral with the housing.

f designates flanges formed on the circuplate (Z to provide guide channels for the melt arms 0.

"i" he rear wall of the housing is detach invention relates to a combined ably secured to the device by means of screws applied to the lugs g. Reversely arranged ratchet teeth j and 7", formed on the ends oi the pinion B, are adapted to coliperate with. corresponding teeth is on the front and rear walls of the housing H.. The operating handle A may he turned in either direction to expand or contract the member to which the rack arms 0 are fitted, and after the reel; arms have been adjusted to the desired positions, the operating handle may he shifted to move the shaft 2' longitudinally,

thus engaging the ratchet teeth i or j with the corresponding ratchet teeth on the h0uslug. .he reversely arranged ratchet teeth constitute two latches one of which is adapted to lock the pinion and rack arms when the device is used as an expander, the other latch beino adapted to lock said parts when the device is used as a contracting device.

Figs. 1 and 2 show the device applied to an expansihle tire rim, the outer ends of the reel; arms 0 being arranged within the rim. After the rim has been expanded by turning the operating handle A, the handle is shifted to more the pinion shaft '5 longi tudinally, thus preventing the rack arms from moving inwardly. T he expansible rim may then he looked in its expanded condition by the plate P (Fig. 1) and the studs 5 (Fig. 2) said studs being adapted to enter the locking; plate P. The rack bar 0, shown in Fig. 5, is provided with a tapered tip or nose n adapted to he forced under the steel rinn's used in some of the Well known. tire holding devices. After the tips n have been fitted to the tire holding ring, the latter may be expanded by turning the operating handle. The rack arm. 0, shown in Fig. 5 is also provided with a lug m, and a memher I adjustahly fitted. to an arm 0. Theelements '1 and m are adapted to engage the inner face of an expansilole tire rim, and they may also he applied to the side faces of tire holding rings t, as shown in Fig. (i. The rings t are expansible and they cooperate with a rim 7 to hold the tirein position.

i claim:- 1. in a device of the character described, a central body, a pinion rotatably mounted in said body, rack arms fitted to said pinion, said rack arms heing movable in response to movements of said pinion, an operating l andle for turning said pinion, and a looking device for locking the rack arms in the positions to which they are adjusted by said 3 v 1,2o7,ee1

pinion, said locking device being under the control of said operating handle.

2. A combined expanding and contracting device comprising a central body, a shaft rotatably mounted in said central body, a pinion, secured to said shaft, rack arms fitted to said pinion, said rack arms being movable in response to movements of said pinion so as to expand or contract the member to which the rack arms are applied, said shaft and pinion beingadapted to turn in one direction when the device is used as on expander and in the opposite direction when used as a contracting device, reversely arranged latches one of which is arranged to lock said rack arms to prevent them from moving inwardly when the device is used as an expander the other latch being adapted tolock said rack arms to prevent them from moving outwardly when the device is used as a, contracting device, one of said latches being adapted to lock said'raclc arms in response to a longitudinal movement said shaft in one direction and the other latch being adapted to lock the rack arms in response to a longitudinal movement of the shaft 1n the opposite direction, and an operating handle secured to said shaft, said pinion and reversely arranged latches being under the control of said operating handle.

3. In a device of the character described, a body provided with a central pinion receiving opening and a series of channels tangential to said central opening, a pinion in said opening, a shaft fixed to said pinion, rack arms arranged in said channels, and ensaid pinion and reversely arranged ratchet clutches on the ends of the pinion coiiperatin'g with corresponding clutches on the interior of said body when the shaft is moved longitudinally to liring one or the other of the ratchet clutches into engagr ment with the corresponding.clutch.
